With LoggingChat(true), is there any way to change (i.e., reduce) the output buffer size? I haven't done enough testing to put a number on it, but at least on OS X, it feels like something in the 2-4k mark, which can be minutes worth of off-peak chatter.

Apart from specific searches, I've scoured CVars and API refs, and came up with nothing. Is there a way to do this, or is it hopelessly hardcoded?
